LUBRICATING DEVICE.

clear, and exact description of the same.

The invention relates to improvements in lubricating devices, and moreparticularly to a form of lubricating device applicable to shafthangers, as described in the present specification and illustrated inthe accompanying drawings, that form part of the same, though it must beunderstood that the invention is not confined to the particular use asshown and described in the present specification and drawings, and itwill be readily seen that it is equally adaptable for the lubrication ofthe journal of any rotating member.

rllhe invention consists essentially of a well supported under thejournal and a strip of textile material extending over and bearingagainst the rotating member, and held in position, whereby a portionthereof extends into the well.

The objects of the invention are to ldevise a simple and cheap devicewhich will efficiently lubricate journal bearings, whereb a continuoussupply of oil will be fed to the journal clear of all grit or foreignmatter, and more especially adapted for the journal bearings ofshafting, whereby the same can be readily applied and supported by theshafting hangers as customary.

A further object of the invention is to provide a lubricator which willhave no moving parts, and may be readily supplied with oil whenrequired.

In the drawings, Figure 1 is a perspective view of the lubricator asapplied to a shaft hanger, showing the cover thereof removed. Fig. 2 isa cross sectional view of the lubricator. F ig. 3 is a longitudinalsectional view of the lubricator.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is a rotating shaft.

2 is the lower half of the bearing in which the shaft 1 rotates, saidshaft being shown in the accompanying drawings as supported by a shafthanger 3, though it must be un- Specicaton of Letters Patent. PatentedM31', 14, 1911.

derstood that the invention is in no way restricted in use to shafthangers, as it will readily be understood that any journal may be formedfor the reception of the lubricating device as hereinafter explained.rIhe lower half of the bearing is formed intermediate of its length witha well 4.

5 is the upper half of the bearing, having the opening 6 therethroughintermediate of its length and immediately over the well 4. The opening6 preferably has a flange 7 extending therearound for the reception ofthe well cover as hereinafter explained.

9 is a strip of felt or other textile material hanging over the shaft 1,so that the ends thereof extend into the well 4, the bearing beingannularly recessed around the interior thereof above the well 4 toaccommodate the strip 9.

is the cover having the section 11 thereof fitting over the extendingportion of the well and the arc section 12 fitting the flange 7 aroundthe opening 6 through the upper half of the bearing, whereby the feltstrip 9 is completely covered, so that dust or foreign matter can in noway get into the well 4. The cover 10 has the apron 13 extendingangularly from the section 11 thereof, whereby the felt strip 9 islapped part way under the shaft 1, so that the said strip where it hangsover the shaft almost com-V pletely encircles the same.

14 is a tea-t or ridge formed on the inner face of the arc-shapedsection 12 of the cover, and engaging the strip 9 where it hangs overthe shaft to prevent the said strip from moving around the shaft andbecoming misplaced.

In the operation of the device, the well 4 is partially filled with oil,so that the ends of the felt strip 9 are immersed, whereby the oil willsaturate the said strip 9, and will be carried through the capillaryaction of the textile material completely around the shaft 1, andeffectually lubricate the shaft which will carry the oil with itthroughout the length of the journal bearmg.

In forming the bearing it is preferable to have the ends thereofcounter-bored at 15, whereby the oil will not reach the extreme end ofthe bearings which are clear of the shaft. It is also preferable to havethe lower half of the bearing formed with the arc-shaped pockets 16 atthe ends thereof to receive the oil which finds its way to theextremities ofthe journal, the' saidipokets Y y 16 communicating withthe well 4L by the cored passages 17 through the lower half of thebearing, so that the oil has a continuous passage through the felt strip9 to the shaft,

and along the shaft to the end of the bearing,whe're it is gathered bythe 'pocket 16, and returned'through the cored passage 17 to the well 4.

In a lubricating device of this kind no grit or foreign matter which maybe in the oilcan in any way Vbe carried to the journal,

i Vas thev strip 9 effectually filters the oil, so

that it is perfectly clear when itY reaches the shafting orv otherrotating member.

It will of course be understood that the cover may be arranged in manyways to j hold" the istrip. 9 to its place, the essential feature of theinvention being the manner in which the said strip is hung over therotating member to almost encircle the same,

Vand still prevented from in any way working therearound.

In applying the lubricating device to a solid bearing, it is onlynecessary to have the bearing recessed for the reception of the feltVstrip,.the said strip being held to its place Lby any convenient means,such as a pointed screw or pin or plates similar to the cover shown inthe accompanying drawings suitably supported at the sides of thebearing.

The apron extending from the cover need not berigid, and it may bepreferable to have the same made of a spring material to clasp the underside ofthe rotating member or shaft.

I What I claim as my invention is:

l. In a device of the class described, the

combination with a journal or similar rotatable member, of a bearingencircling said journal and having a well formed in the lower halfthereof intermediate of its length Aand an opening' through the topVthereof into ,said well, a strip of textile material hanging oversaidjournal and depending into said well, of a cover itting the open upperside of Vsaid bearing and having an apron extendjing'therefrom againstthe depending end of said strip and holdingY th-e same undery saidjournal. Y

2. In a device of the class described, the combination with a vjournalor similarly rotatable-fmember, of a bearing encircling said journal'and having a well formed in the and an opening through the top thereofinto said well, a strip of textile material hanging over said journaland depending into said well, of a cover fitting the open upper side ofsaid bearing and having an apron extending therefrom against thedepending end of said strip and holding t-he same under said journal anda teat or ridge projecting from said cover and contacting with saidstrip over said journal.

3. In a devicev of the class described, the combination with a journalor similar rotatable member, of a bearing encircling said journal andhaving a well formed in the lower half thereof intermediate of itslength and an opening through the top thereof into said well andcounter-bored extremities and arc-shaped pockets formed at theextremities of# said bearing and communicating through suitable coredpassages with said well, a strip of ytextile material hanging oversaidjournal and depending into said well, a cover fitting the open upperside of said bearing and having an apron extending therefrom against thedepending end of said strip and holding the same under said journal.

z ..In a device of the class described, the combination with a journalor similar rotatable member, of a bearing encircling said journal andhaving a well formed under the lower half thereof intermediate of itslength and an opening through the top thereof into said well andcounter-bored extremities and' arc-shaped pockets formed at theextremities of said bearing and communicating through suitable coredpassages with said well, a strip of textile material hanging over saidjournal and depending into said well, of a cover fitting the open upperside of said bearing and having an apron extending therefrom against thedepending end of said strip and holding the sameunder'said journal and ateat or ridge projecting from said cover and contacting with said stripover said journal.
